For example, there's a bolted thin face-crack with a desparate looking start (and a really high first bolt), which I cannot identify, as well as some other lines nearby (and further around) which look like they could be quite good.

The bolted crack is the mitch project, the route right is gas leak slab, the route left is alpaca corner, the arete left again is another project.
Much further right are about 20 older mixed routes, some look ok

Hehe, you read my mind. I'd heard it might have been an open project and thought about giving it a shot.. I sorta figured that the only way it'd still be a project was if the crux was hidden somewhere at the top =P
